SANITARY NOZ ZLE Filed Oct. 18, 1930 Patented Apr. 26, 1932 UNITEDSTATES PATENT oFFIcE JOHN E. ROUSEK, 'OF CHICAGO, ILLINOIS SANITARYNOZZLE Application filed October 18, 1930.

My invention relates to hose nozzles and particularly to nozzles forhose for filling water tanks on railway cars or tanks in like situationswhere the hose when not used lies upon the ground so that it is likelyto become soiled or fouled. The principal object of the invention is toconstruct the nozzle so that the portion thereof which enters thefilling opening of the tanks is protected, when the hose is not in use,against dirt and the like whereby the contamination of the water in thetank from this source is prevented.

The invention is illustrated in a preferred embodiment in theaccompanying drawings,

' in which Fig. l is an'end View of a water tank arranged under the bodyof a railway car, a part of which is shown in section, illustrating onetypical way of using the hose nozzle of this invention.

Fig. 2 is a side elevation of the nozzle in a position of non-use on theground.

Fig. 8 is a longitudinal sectional elevation of the nozzle, on a largerscale than Figs. 1 and 2, showing the nozzle member collapsed ortelescoped within the protecting sheathing member.

Fig. 4 is a cross sectional view on line 44 of Fig. 3.

Fig. 5 is a longitudinal sectional view, similar to Fig. 3, butillustrating the nozzle member projected from the sheathing member inposition for use of the nozzle; and

Fig. 6 is a view in perspective of a cap member for the rear end of thesheathing.

Referring to the drawings 10 designates the flooring of a railway carand 11 a water tank suitably supported under the flooring of the car andformed with a. filling opening 12.

The nozzle comprises a tubular sheathing l3 and a nozzle 14 whichlatter, when the nozzle is not in use, is telescoped within thesheathing so that its forward or discharge end is protected againstcontact with dirt or other contaminating matter. Preferably the nozzlemember is formed with an extension 15 beyond the rear end of thesheathing 13 which may be provided with a cock valve 16, of any suitableconstruction, provided with Serial No. 489,620.

a nipple 17 for attachment to the hose 18 (Figs. land 2).

The sheathing 13, is provided, internally, at the discharge end of thenozzle with a bushing 19, which serves to guide the forward end of thenozzle member, the latter being provided, preferably, with a collar 20which serves to guide the nozzle in the sheathing;

a coiled spring 21 being arranged between bushing-'19 and collar 20which tends vto re- 00 tract the nozzle member 14 within the sheathingas shown in ,Fig. 3. A suitable locking means is provided for holdingthe nozzle member 14 in its position of use, that is with its endprojected from the sheathing as shown he in Fig. 5. To this end the rearextremity of the sheathing is provided with a cap 22 formed with anopening 23 (Fig. 6) and with diametrically arranged notches 24, 24, theopening 23 being for the rear portion 15 of the nozzle member and thenotches 24for lugs 25, 25 which, when the nozzle is turned in thesheathing will engage the flanged portion 26 of the cap 22, as shown inFig. 5.

The sheathing is providedwith means for supporting the nozzle structure,when not in use, so that its discharge end will be raised above theground. Preferablythe cap 22 has welded thereto an annular disk 27 whichserves this purpose, as best shown by Fig. 2.

' Preferably when the nozzle member is collapsed or telescoped withinthe sheathing the forward extremity of the nozzle member is set back forsome little distance from the forward end of the sheathing.

WVhen the filling hose is to be used, for eX ample, for filling a tanksuch as the tank 11 (obviously the nozzle of my invention might be usedfor other similar purposes), the sheathing 13 is pulled back over thenozzle 0 member l4, l5 and turned to align the lugs 25 with the notches24, the notches brought over the lugs and the sheathing turned so as toengage the lugs with the flange 26 of the cap 22. This projects theforward end of the nozzle member 14 beyond the sheathing 13. This partof the nozzle is introduced into the filling opening 12 of the tank 11and the cook 16 opened. When the tank has been filled the userturns thesheathing on the nozzle until lugs 25 align with notches 24 whereuponspring 21 telescopes the forward portion 14 of the nozzle member withinthe sheathing. The hose may be dropped upon the ground but, because ofthe position of the supporting disk 27, the discharge end of the nozzlewill be kept from contact with the ground.

Realizing the possibility of modifications in details of construction, Iwish it to be understood that all modified forms of the invention areintended to be claimed Within the scope of the appended claims. 7

I claim:

1. A hose nozzle comprising a nozzle member, a sheathing telescopicallyarranged so that the discharge end of the nozzle is enclosed by thesheathing when not in use, and a spring which tends to retract thenozzle in .the sheathing.

2. A hose nozzle comprising a nozzle member, a sheathing telescopicallyarranged so that the discharge end of the nozzle is enclosed by thesheathing when not in use, a spring which tends to retract the nozzle inthe sheathing, and means for locking the nozzle'in its extendedposition.

, .8 A hose nozzle comprising a nozzle member and a sheathingtelescopically arranged so that the discharge end of the nozzle isenclosed by the sheathing when not in use, and .a support on thesheathing which holds the discharge end of the nozzle out of contactwith the ground when the nozzle is lying on the ground out of use.

. 4. Ahose nozzle comprising a nozzle member, a sheathing telescopicallyarranged so that the nozzle is enclosed by the sheathing when not inuse, and a supporting disk on 1 .the sheathing arranged to hold thedischarge end of the nozzle out of contact with the ground.

.5. A hose nozzle comprising a nozzle member, a sheathing telescopicallyarranged so that the nozzle is enclosed by the sheathing when not inuse, a spring which tends to retract the nozzle in the sheathing, and asupport on .the sheathing which holds the discharge end of the nozzleout of contact with the ground when the nozzle is lying on the groundout of use v 6. A hose nozzle comprising a nozzle member, a sheathingtelescopically arranged so that the nozzle is enclosed by the sheathingwhen not in use, a spring which tends to retract the nozzle in thesheathing, and a supporting disk arranged on the sheathing so that whenthe nozzle is lying on the ground out ofuse its discharge end is keptout of contact with the ground.
